ELECTRIC GAS Application led October 19, 1927.

This invention apporta-ins to new and useful improvements in circuitmakers and breakers, and more particularly to a. novel switch especiallyadapted for use in conjunction with electric gas lighters, suc-h as areadapted to be mounted on electric ranges.

An important object of the invention is to provide a switch which willbe of low cost of manufacture, and which will in use be positive actingand not susceptible to the development of defects which would tend tooccur in al more complicated structure.

Various other important objects of the invention will become moreapparent to the reader after the following specification is read.

In the drawings z- Figure l represents a side elevational view of theswitch mount.

Fig. 2 represents a side eleva-tion of the switch mount showing thereverse side from that shown in Fig. l.

Fig. 3 represents a cross. sectional view through the switch housingshowing the switch mount therein.

Fig. A represents an edge elevational view of the switch mount.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that the base A has a hard rubber strip B attached acrossthe top by means of screws B and B2. This holds the contact spring F andacts as one contact point from the primary electric current. The base Aalso has a suitable hole for the shaft B which oper ates the lever G bya clockwise turn of the knob C.

Attached to the threaded end of the shaft B is the spring D t-he sameextending through a small hole at a point midway of the shaft D andconnects in the screw D2 on the base A. But the shaft D and the lever Greturns to normal position and the spring acts as a conductor for theprimary current from the screw D2 thus completing the primary circuitwhen the knob C, shaft D and lever G are turned clockwise.

The screw D2 also acts in the lever G to the shaft D. The lever G has acentral open- LIGHTER Serial No. 227,321.

which receives the shaft D and is secured he shaft D by the set screwG2. The lever and the copper wire along the under side thereof, which issupported in place by inserting the ends thereof through openings at oneend and the center thereof. This acts as a connecting rod for thesecondary high tension current which closes the circuit between E andA', A2, A3, A4, A5, and AG when the shaft D is turned clockwise.

A stop G3 is employed for the lever G and against this, the lever maynormally engage, and as can be clearly shown in the drawing, the stop Glis provided for the lever G when the latter is at its opposite extent oftravel.

The contact points A, A2, A3, A4, A5, and A6 are constructed of smallpins or screws secured at a specified distance apart, and

from the contact G4E so as not to allow spark- 70 ing.

Fig. 3 shows the complete switch as is also shown in Figs. 2 and 4, andthe casing for the switch is denoted by numeral I and is secured to thegas pipe of the range by means 7 of the clamp H.

The clamp H is grounded by a wire to the screw F extending from thespring F. In operation the gascock on the range or stove, forcontrolling the gas burner is turned on in the usual manner, andsubsequently to this, the switch is turned on to close the primarybattery circuit. Thus a spark is produced across the ranOe burner,igniting the lgas at the particular burner from which gas is issuing.

Having thus described my invention, what I claim as new is In anelectric switch comprising, a. base, a shaft journaled through the baseand being adapted to project beyond opposite sides thereof, an armsecured to one end of tho shaft, a spring contact on the base, a rigidcontact on the said arm adapted for wiping engagement with the saidspring contact, an elongated contact strip engaged longitudinally on thearm, an arcuate contact strip on the base, and a plurality of contactmembers on the base arranged concentrically with respect to the arcuatecontact strip, said cc-n-
